How are you sure that wget as finished and the wget process has terminated? I recommend using the logging options of wget plus adding some logging/syslog output to your Perl script as well - print statements should also be enough, as cronmails those to you.

because the first file (from store 1) is exactly where it's supposed to be.
i do use basic logging in my script (see above), but after the first wget, i don't get anything....
(and running the script manually works splendid, so i think i didn't mess up URLs and such)
